2.1 again thank you |
I like math, and I'm bored so here it goes... (turns out all your answers were wrong or am I just wrong...?)
1. $30,800 is his share after 12% in taxes so it's 88% of the before taxes... so 30,800/.88 = $35000 before taxes. 4 heirs x 35,000 per heir =
$140,000. Answer in bold.
2. You work backwards. 2004 they sold it for $614,000. That year it had increased $50,000 so:
614,000 - 50,000 = $564,000.
It was $564,000 after increasing by 20% so... 564,000/1.2 =
$470,000
Note: You can check these answers by reworking the problem forwards!
Check - $470,000 house increases by 20% so 470,000 x 1.20 = 564,000 plus 50,000 = $614,000
3. easy easy... $41,200 x 1.028 =
$42,374.16
4. if 13.2 pounds of rice can be purchased for $4.12, how many pounds of rice can be purchased for $15(round to the nearest tenth) ?
13.2 pounds of rice = $4.12
How much per each pound of rice? 4.12/13.2 = $.312121 per pound of rice
So you have $15 to buy some rice... 15/.312121 =
48.06 pounds of rice (rounded from 48.0582524)
How do you get 2.1 pounds for $15 when $4.12 can buy 13.2 pounds...? You can look at it and tell it's over 3 times more rice since 15 is more than 3 times 4.12. A faster and possibly more accurate way to solve is setting up proportions (keep what's on top/bottom consistent for each):
4.12/13.2 = 15/x
Cross multiply : 4.12x = 198
198/4.12 =
48.1 pounds (rounded from 48.0582524)
